Anthracnose
scouted Oct. 8, 2024
- Scientific Name
- Colletotrichum destructivum
- Background
- Soybeans in Pitt County were observed to be affected by disease, with 65% of the field affected, and a sample was submitted to the PDIC for diagnosis.
- Conclusion
- The issue was identified as Anthracnose, caused by the fungus Colletotrichum. While usually a disease that shows in the stems and the petioles, it can also cause leaf curling and reddening of the veins. Warm, wet weather favors infection and disease development. Crop rotation and tillage can reduce inoculum, while foliar fungicides will reduce disease, but it's usually not profitable.
